4 Claims.

This invention relates to improvements in books of the kind wherein, in order to keep abreast of the times', provision is made for appending periodically published pamphlets of current text matter, the pamphlets having tongues or iiaps which are adapted to be inserted in pockets formed or provided upon the covers of the books and for this reason being commonly referred to as pocket supplements.

Such supplements may vary as to initial size but, as a general rule, increase in thickness with successive issues. In any event if their thickness is, or becomes, substantial, as is frequently the case, they may impose a strain upon the covers of the books sufficient to weaken or deform them. The principal object of the invention, therefore, is to guard against this, this object contemplating a book which is so designed that compensation may be made for the thickness Iof individual supplements as and in the degree required.

A further object is to provide a book of the character generally described which in shape and appearance resembles a` conventionally bound book and which will retain such characteristics regardless of the thickness of the appended supplement.

The invention is illustrated in the accompanying drawing in which:

Figure 1 is a perspective View of a book embodying the features of the invention.

Figures 2 and 3 are end views of the book illustrating the manner in which supplements of diierent thicknesses are accommodated.

The book, as illustrated, may be, and preferably is, bound in a conventional manner and it includes the usual pocket 4 which is suitably formed or provided upon the inside of the back of the cover and into which the tongue or flap of a supplement may be inserted. -In accordance with the invention signatures of dummy pages 5 are bound in back of the permanent pages 6 which bear the original text matter of the book, each of the dummy pages being removable by tearing along a line of perforations 'l formed adjacent the bound edge. A Signatura as understood in the bookbinding art and as herein used, comprises a plurality of pages formed by folding a single sheet and trimming the connected edges along three sides, the fourth side being adapted to be stitched or otherwise bound, and it may, for example, include 1S, 32 or 64 pages. The number of dummy pages thus provided is preferably predetermined so that their total thickness is substantially the same as the estimated maximum thickness of the final supplement to be accommodated. For example, if a revised edition should be contemplated in ten years then the estimate of the maximum thickness of the supplement would, of course, be based upon this period of time. 'Ihe dummy pages are preferably separated from the permanent pages by a colored or otherwise readily distinguishable page il.

The supplements which are indicated at 9 may be conventional. As illustrated, therefore, each is removably secured in the book by a tongue or ap which is preferably of relatively stiff material and which is adapted to be inserted into the pocket 4 provided for this purpose. If the supplement is of substantial thickness, as is the case in the illustrated embodiments, such thickness may be compensated for by tearing out the proper number of dummy pages, that is to say the number of pages having a total thickness which corresponds approximately to that of the supplement. For example, in the embodiment illustrated in Figure 2 space has been provided for the supplement by removing substantially half of the dummy pages whereas in Figure 3 the supplement is of the estimated maximum thickness and hence all of the dummy pages have been removed.

From the foregoing it will be apparent that in each instance the supplement occupies the space originally occupied by the dummy pages which have been removed. Hence the thickness of the book remains substantially constant and regardless of the thickness of the supplement no additional strain is imposed upon the cover. The accommodation of the supplements in` the manner described, therefore, does not weaken or otherwise impair the cover or alter to any appreciable degree the original shape or appearance of the book.

I claim as my invention:

l. A book adapted to accommodate supplements of the character described and including a cover having front and back boards between which sections of permanent and dummy pages of substantially the same dimensions are bound, the thickness of the section of dummy pages corresponding to a predetermined maximum thickness of supplement, the dummy pages being designed to be removed in numbers corresponding to the thickness of individual supplements, whereby the thickness of the material 4between said cover boards including the permanent pages, the dummy plages and a supplement can be maintained constant with supplements of different thicknesses.

2. A book adapted to accomodate supplements of the character described and including a cover having front and back boards between which sections of permanent and dummy pages of substantially the same dimensions are bound, the thickness of the section of dummy pages corresponding to a predetermined maximum thickness of supplement, the dummy pages being designed to be removed in numbers corresponding to the thickness of individual supplements, whereby the thickness of Ithe material between said cover boards including the permanent pages, the dummy pages and a supplement can be maintained constant with supplements of different thicknesses and means for removably securing said supplements in the position originally occupied by those of the dummy pages which have been removed. v

3. A book adapted to accommodate supplements of the character described and which to this end has one of its cover boards formed with a pocket into which tongues or flaps carried by the supplements may be inserted, said book including sections of permanent and dummy pages of substantially the same dimensions which are bound between said cover boards, the thickness of the section of dummy pages corresponding to a predetermined maximum thickness.. of supplement, the dummy pages being perforated adjacent their bound edges and being removable, by tea-ring along said perforations, in numbers corresponding to the thickness of individual supplements, whereby the thickness of the material between said cover boards including the permanent pages, the dummy pages and a supplement can be maintained contant with supplements of diiferent thicknesses.

4. A book adapted to accommodate supplements of the character described and which to this end has one of its cover boards formed to carry an insertible and removable supplement, said book including sections of permanent and dummy pages of substantially the same dimensions which are bound between said cover boards, the thickness of the section of dummy pages corresponding to a predetermined maximum thickness of supplement, the dummy pages having binding parts and being formed for detachment from their binding parts and being removable, by detachment, in numbers corresponding to the thickness of individual supplements, whereby the thickness of the material between said cover boards including thepermanent pages, the dummy pages and a supplement can be. maintained constant with supplements of different thicknesses and the binding parts from whichv dummy pages have been detached will lie behind the supplement occupying the space originally occupied by said dummy pages.
